▎ 摘  要

NOVELTY - The screen has a polymer elastomer is a poly two methyl silicone (PDMS), polyurethane elastomer (TPU), silicone rubber or polyurethane rubber and other materials. The upper layer graphene and the lower layer graphene are transmitted to a main control chip (207) through the peripheral circuit and the interface chip. The main control chips according to an interface chip a (204) and interface chip b (206) input information is provided. The touch position and the corresponding touch pressure of the capacitive touch screen are obtained. USE - Graphene capacitive touch screen with pressure sensing. ADVANTAGE - The touch screen has advantages of folding, high sensitivity, light and light, high transmittance, high conductivity, low cost, green environmental protection, and lays the foundation for a new type of touch equipment. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene touch screen. Upper layer graphite (201) Vertical conduction area (202) Interface chip (204,206) Periphery circuit (205) Main control chip (207)
